Abstract:

This project will investigate the influence of quality, quantity and diversity of basal energy input on the biodiversity, structure and functionality of cave stream food webs. The current study will compare the influence of the standing stock of macronutrients (C, N and P) from basal resources and their uptake rate by consumers on the food web characteristics in a sinking-cave stream. Strong structural and functional alterations of the envisaged food webs, as the decrease of biodiversity, are expected directly with the gradual decrease of basal resources’ quantity, quality and diversity, as the river flows through the cave. It is expected that the decrease of quantity, quality and diversity of basal energy input to affect the mass of nutrients cycled among trophic levels, consumer homeostasis and secondary production. The diminishing basal energy quality will equally induce a winnowing effect on the web architecture, which will be oversimplified compared to surface sectors, explaining the current composition of cave stream biodiversity. These aspects will comprise lower trophic diversity, increased trophic niche overlap among taxa, omnivory of consumers and equally of instraspecific competition for food compared to surface sectors of streams.

Biodiversity and the provision of multiple ecosystem services in current and future lowland multifunctional landscapes Call name:
2012 - 2017

Role in this project: Key expert

Coordinating institution: Queen Mary , University of London

Abstract:

Biodiversity underpins many ecosystem services - the benefits that people gain from the natural world, such as clean water, storage of greenhouse gases, crop pollination, and a pleasant and fulfilling environment. Yet the way in which biodiversity affects different services is poorly understood scientifically, especially when considering the real world rather than small-scale studies. Lowland agricultural landscapes are particular 'crunch' points, where food security needs to be balanced with the provision of other ecosystem services against the backdrop of a changing climate. Many of these services are in conflict, such as crop production, climate regulation and cultural services. Already, agricultural landscapes show signs of degradation, with consequences for their biodiversity and the provisioning and resilience of services.

Mechanism of alien crayfish invasion in the lower Danube Call name: Projects for Young Research Teams - RUTE -2014 call

Abstract:

Nowadays, the native crayfish species in Europe face major threats because of the introduction of north-American crayfish species in the last two centuries. The most successful invasive crayfish species, the spiny-cheek crayfish (Orconectes limosus) reached the lower Danube (Romanian territory) in 2008, and is advancing further downstream towards the Danube Delta. There are first results suggesting a serious decline in the abundance of indigenous narrow-clawed crayfish (Astacus leptodactylus) in the invaded areas. Therefore, the active invasion front along the Romanian Danube offers a unique opportunity for scientists to elucidate the drivers behind the invasion success and the potential impact on local ecosystems. This project aims to reveal the reproduction strategies and habitat selection of invasive and indigenous crayfish species, and assess the occurrence of the crayfish plague (Aphanomyces astaci) by applying various modern techniques (real-time PCR, sequence analysis, stable isotopes). Combining international scientific expertise in an integrative approach, this project has the potential to achieve relevant results suggesting scientifically-sound strategies to protect indigenous crayfish species and biodiversity.

The role of lateral exchange in modulating the seaward flux of carbon, nitrogen and phosphorus. Call name:
2012 - 2015

Role in this project: Key expert

Abstract:

A major task of this research project was to establish the extent to which C, N and P limit the growth and reproduction of invertebrates and fish in these streams. Moreover, the food web architecture was modeled, as the nutrient cycling among feeding guilds and trophic levels.
